Exporting idb's with less then 100 functions fails
Exporting idb's with less then 100 functions fails

Just a small bug causing the script to fail. 
At https://github.com/joxeankoret/diaphora/blob/master/diaphora.py#L1483 where 
it tries to report progress for large IDBs , the calucaltion in `if` statement will
fail with divide by zero if `total_funcs` is less then 100. 

Cheers,
